brown valve cover ZC - has "ZC" & serial number stamped on top of block next to transmission, right by the starter (not on front of block), doesn't have valve cover bolts at edge - black valve cover from 88-89 integra D16A1 will bolt right on
The 1986-89 Integra engines bolt in to the 3rd gen Civic/CRX.
